Description

Technical Field

[0001] The utility model relates to the technical field of punching machines, in particular to a protection device for die parts of punching machines. Background Art

[0002] Traditional punching machines, mechanical punching machines, table punching machines, precision punching machines, high-speed punching machines and the most advanced servo punching machines all rely on punching molds for normal use. The punch is one of the core parts of the upper mold of the punching mold. The punch moves back and forth with the upper mold of the punch driven by the slider, and cooperates with the lower template material to deform and cut, etc. to complete the stamping process.

[0003] According to the Chinese patent publication number CN211101164U, the patent provides a protective device for mold parts for a punching machine, including a base, a cushion block is symmetrically fixedly arranged on the upper surface of the base, and a support plate is connected to the upper part of the cushion block; a mounting groove is opened on the upper part of the support plate, and mounting holes connected to the mounting groove are evenly opened on the support plate; a first buffer spring is installed in the mounting hole, and a bearing plate matching the mounting groove is arranged on the side away from the mounting hole of several first buffer springs. By installing the first buffer spring in the mounting hole and a bearing plate matching the mounting groove is arranged on the side away from the mounting hole of several first buffer springs, damage to the mold due to force and vibration during transportation can be avoided.

[0004] The above technology uses a buffer structure to improve the protection ability of the mold during transportation. However, the weight of the mold varies according to the size of the mold. This causes the lighter mold to shake easily during transportation, reducing the buffering effect, while the heavier mold will hinder the reset performance of the buffer spring, resulting in a reduced buffering effect. It is difficult to prevent damage caused by mold collisions by relying solely on the buffer spring. In view of this, we propose a mold component protection device for a punch press.

[0015] (1) The utility model provides protection through protective frame 1 and protective frame 2, which can shield the edge of the stamping die in space, thereby preventing the stamping die from bumping and falling, and preferentially destroying protective frame 1 and protective frame 2.

The U-mouth of each U-shaped locking block 67 is aligned with the adjacent sliding rod 64, and the U-mouth of the U-shaped locking block 67 is inserted on the sliding rod 64 to limit the bottom of the limit plate 66, so that the limit spring 1 65 prevents elastic expansion and contraction. The U-shaped locking blocks 67, extension arms 68 and L arms 69 in the two slide slots 63 are symmetrically arranged, and a spring 2 is elastically connected between the U-shaped locking block 67 connected to each L arm 69 and the inner wall of the slide slot 63 where it is located. There are two protective mechanisms 6, and the other protective mechanism 6 is installed on the other side of the stamping die 4. The two protective mechanisms 6 are symmetrically arranged.

[0026] In this embodiment, the protective frame 1 5 and the protective frame 2 7 are used for protection, and can block the edge of the stamping die 4 in space, so as to prevent the stamping die 4 from being bumped or falling, and preferentially destroy the protective frame 1 5 and the protective frame 2 7, thereby further improving the stability during transportation and further improving the force buffering capacity.

[0027] Embodiment 2

[0028] See also Figure 1-4On the basis of the first embodiment, the utility model provides a technical solution: preferably, a punching table 2 is installed in the processing area of ​​the punching machine body 1, and a stabilizing mechanism 3 is arranged on the punching table 2, and the stabilizing mechanism 3 includes a mounting frame 31, and the mounting frame 31 is installed on one side of the outer wall of the punching machine body 1, and a hydraulic rod 32 is installed on the top of the mounting frame 31, and the hydraulic rod 32 is telescopically adjusted to adapt to stamping dies 4 of different sizes, and an L-shaped clamping plate 33 is fixedly connected to the inner rod of the hydraulic rod 32, and one end of the L-shaped clamping plate 33 is slidably connected to the groove of the punching table 2, and an adjustment groove 34 is opened on the other end of the L-shaped clamping plate 33, and the inner wall of the adjustment groove 34 slides An unlocking slider 35 is connected, and there are two stabilizing mechanisms 3. The two stabilizing mechanisms 3 are both installed on the stamping machine body 1 and are symmetrically arranged with each other. The unlocking sliders 35 in the two stabilizing mechanisms 3 are respectively aligned with the extension arms 68 in the two protective mechanisms 6, and each unlocking slider 35 is respectively abutted against the adjacent extension arms 68. The protective frame 1 5 is slidably sleeved on the outer wall of the stamping die 4, and the bottom of the stamping die 4 is fixedly sleeved with a protective frame 2 7. The protective frame 2 7 increases the contact area of ​​the stamping die 4. The inner walls of the two L-shaped clamps 33 abut against the outer walls of the protective frame 2 7, and the stamping die 4 is clamped between the two L-shaped clamps 33.

[0029] In this embodiment, when the L-shaped clamp 33 is clamped, each unlocking slider 35 smoothly rests on the corresponding extension arm 68, thereby squeezing the spring 2, prompting the U-shaped locking block 67 to release the limit on the limit plate 66, and preferentially contacts the protection frame 5 during the stamping operation, and performs buffering protection under the elastic force of the spring 65. When the stamping die 4 is disassembled and transported, the U-shaped locking block 67 is reset and inserted on the slide rod 64 to limit the limit plate 66, thereby increasing the supporting force of the protection frame 5 on the stamping die 4 and performing rigid protection on its periphery.

[0030] Working principle: The distance position between the two L-shaped clamps 33 is adjusted by telescopic hydraulic rod 32, so as to adapt to stamping dies 4 of different sizes for stable clamping. Contracting the hydraulic rod 32 can open the L-shaped clamp 33, so that the stamping die 4 can be quickly disassembled for transportation. The entire stamping die 4 is protected by protective frame 1 5 and protective frame 2 7, which can block the edge of the stamping die 4 in space to prevent the stamping die 4 from bumping or falling, and preferentially destroy protective frame 1 5 and protective frame 2 7 to avoid serious structural damage to the die itself. The contact area of ​​the stamping die 4 is increased by protective frame 2 7, and the stability during transportation is further improved. The contact area of ​​the stamping die 4 for force buffering during stamping is increased by protective frame 1 5, and the buffering capacity is further improved, which improves the safety during stamping operation and reduces the damage to the die caused by stamping vibration. Stamping dies 4 of different sizes can be installed with protective mechanisms 6 of matching sizes to improve the protection capability of the stamping die 4.

[0031] During the stamping operation, the unlocking slider 35 is slid along the adjustment groove 34, so that when the L-shaped clamp 33 is clamped, each unlocking slider 35 smoothly rests on the corresponding extension arm 68, thereby squeezing the spring 2, causing the U-shaped locking block 67 to slide in the slide groove 63 away from the corresponding slide rod 64, thereby releasing the limit on the limit plate 66. At this time, the stamping will preferentially contact the protective frame 5 through the upper pressure plate, and buffer under the elastic force of the spring 65, and then make the upper pressure plate contact the stamping die 4 to complete the component forming, which plays a role in buffering and protecting the stamping die 4 during stamping.

[0032] When the stamping die 4 is disassembled and carried, since the extension arm 68 loses the abutment of the unlocking slider 35, it is reset by the elastic force of spring 2, prompting the U-mouth of the U-shaped lock block 67 to be inserted on the slide rod 64 to limit the bottom of the limit plate 66, thereby limiting the spring 1 65 to prevent elastic expansion and contraction. At this time, the protective frame 1 5 cannot slide by the deformation of the spring 1 65, so it is supported on the periphery of the stamping die 4 for rigid protection.
